Description

  The present invention relates to a technology for reproducing content such as images and sounds on a mobile terminal.

  Various techniques for reproducing contents such as images and sounds on mobile terminals have been conventionally proposed. For example, Patent Document 1 discloses a technique for distributing content according to the position of a mobile terminal to a mobile terminal registered in advance as a distribution target.

Japanese Patent Application Laid-Open No. 2002-351905

  For example, in a transportation system such as a train or a bus, a guidance voice for guiding a user about information about getting on / off or transfer is reproduced at any time. If it is possible to provide the mobile terminal of the user with content such as a character string of the pronunciation content of the guidance voice or a translation for each emission of the guidance voice, for example, it is difficult to understand the language of the guidance voice. Foreign users are also useful because they can grasp the contents of the guidance voice. However, under the technology of Patent Document 1, provision of content linked to the actual sound emission of the guidance voice is not assumed. In consideration of the above circumstances, the present invention has an object of causing a mobile terminal to reproduce content related to a guidance voice in conjunction with the emission of the guidance voice.

  In order to solve the above problems, an information providing system according to a preferred aspect of the present invention interlocks distribution information for reproducing content related to a guidance voice with the emission of the guidance voice by a sound emitting device. And an information distribution unit for transmitting to the mobile terminal.

  An information providing system according to another aspect of the present invention is registered as providing instruction means for generating an instruction to provide content related to a guidance voice for each emission of the guidance voice, and as a provision target of content related to the guidance voice. The mobile terminal is provided with an information distribution means for transmitting distribution information for reproducing the content relating to the provision instruction. In the above configuration, the provision instruction of the content related to the guidance voice is generated for each sound emission of the guidance voice, and the distribution information for reproducing the content related to the provision instruction is transmitted to the mobile terminal registered as the provision target. Ru. Therefore, it is possible to reproduce the content related to the guidance voice on the mobile terminal in conjunction with the emission of the guidance voice.

  The information providing system according to a preferred aspect of the present invention receives from the mobile terminal the guidance identification information acquired by the mobile terminal at the place where the guidance voice is emitted, and guides the guidance target specified by the guidance identification information. A registration processing unit is provided which registers the mobile terminal as a provision target of content related to voice. In the above aspect, since the mobile terminal which acquired the guidance identification information at the place where the guidance voice is emitted is registered as the provision target of the content, it is limited to the mobile terminal located at the place where the guidance speech is emitted. It has the advantage of being able to provide content. For example, in the configuration where the registration processing means receives from the mobile terminal the guidance identification information acquired by the mobile terminal by capturing the information image installed at the location where the guidance voice is emitted, or in the location where the guidance voice is emitted It is preferable that the registration processing means receives, from the mobile terminal, the guide identification information transmitted to the mobile terminal by the short distance wireless communication.

  An information providing system according to a preferred aspect of the present invention is a reproduction processing means for supplying an audio signal including an acoustic component of a guidance voice and an acoustic component of identification information of content related to the guidance voice to a sound emitting unit; And an information extraction unit that extracts identification information from the acoustic signal, and the provision instruction unit generates a provision instruction of the content designated by the identification information extracted by the information extraction unit. In the above aspect, the guidance voice is emitted by the supply of the acoustic signal to the sound emission unit, while the identification information included as the acoustic component in the acoustic signal is extracted by the information extraction unit and the provision instruction is generated. Ru. That is, the acoustic signal is shared by the emission of the guidance voice by the sound emission unit and the extraction of the identification information by the information extraction unit. Therefore, it is possible to easily and reliably interlock the emission of the guidance sound by the sound emission unit and the generation of the provision instruction by the provision instruction unit (and the reproduction of the content by the mobile terminal).

  An information providing system according to a preferred example of a configuration using an acoustic signal containing an acoustic component of a guidance voice and an acoustic component of identification information comprises a management terminal including an information extraction unit and a provision instruction unit, and a reproduction processing unit Sends a sound signal to the management terminal by wire. In the above aspect, an acoustic signal containing the acoustic component of the guidance voice and the acoustic component of the identification information is transmitted from the reproduction processing means to the management terminal by wire. Therefore, there is an advantage that the identification information can be specified from the acoustic signal with high accuracy even when the sound volume of the acoustic component is sufficiently suppressed so that the acoustic component of the identification information is not easily perceived.

  In a preferred example of the configuration using an acoustic signal containing the acoustic component of the guidance voice and the acoustic component of the identification information, the acoustic signal is lower than the upper limit value of the reproduction band by the sound emitting portion in the original acoustic signal representing the guidance voice It is the signal which synthesize | combined the 1st acoustic signal which suppressed the acoustic component of the utilization band over the predetermined width | variety by the side of a zone, and the 2nd acoustic signal showing identification information as an acoustic component in a utilization band. In the above aspect, since the acoustic component in the utilization band where the acoustic component of the identification information D is synthesized among the original acoustic signal of the guidance voice is suppressed, even when the volume of the acoustic component of the identification information is sufficiently suppressed. There is an advantage that identification information can be identified with high accuracy from an acoustic signal.

  The information providing system according to each of the above aspects is realized not only by a dedicated electronic circuit but also by cooperation of a general-purpose processing unit such as a CPU (Central Processing Unit) and a program. The program of the present invention may be provided in the form of being stored in a computer readable recording medium and installed on the computer. The recording medium is, for example, a non-transitory recording medium, and is preferably an optical recording medium (optical disc) such as a CD-ROM, but any known medium such as a semiconductor recording medium or a magnetic recording medium may be used. Recording media of the form Note that, for example, the program of the present invention may be provided in the form of distribution via a communication network and installed on a computer.

  The present invention can also be specified as an operation method (information provision method) of the information provision system according to each aspect described above. Specifically, an information providing method according to a preferred aspect of the present invention generates an instruction to provide content related to a guidance voice for each sound emission of the guidance voice, and a provision target of content related to the guidance voice. Transmitting the distribution information for reproducing the content relating to the provision instruction to the mobile terminal registered as.

The mobile terminal 20 and the management terminal 14 can communicate with the information providing device 16 via the communication network 18. The voice guidance device 12 emits a voice for guidance on a transportation facility (hereinafter referred to as “guidance voice”) to the user HA in the vehicle M. The guidance voice is, for example, a voice for guiding the getting on / off of transportation (name of a stop point such as a train station or a bus stop), transfer, fare, operation status (for example, presence or absence of delay), surrounding sightseeing spots and the like.

  In the information providing system 100 according to the first embodiment, as schematically illustrated in FIG. 1, for each emission of guidance voice by the voice guidance device 12, the provision instruction P of the content C related to the guidance voice is Distribution information Q transmitted from the management terminal 14 to the information providing apparatus 16 and including the content C designated by the provision instruction P is transmitted from the information providing apparatus 16 to the mobile terminal 20. The content C distributed from the information providing device 16 to the mobile terminal 20 is a voice or an image (for example, a still image, a moving image, a character string) related to the guidance voice. For example, a character string representing the pronunciation content of the guidance voice and various information such as a character string or a voice obtained by translating the language of the pronunciation content into another language are provided to the mobile terminal 20 as the content C. In the first embodiment, provision of guidance regarding a plurality of guidance targets is assumed. An object of guidance means an object of guidance, and is typically a place where guidance is provided. In FIG. 1, the vehicle M of the transportation system is illustrated as the guidance target, but in practice, the voice guidance device 12 and the management terminal 14 are installed for each of a plurality of guidance objects (for example, for each vehicle M of the same transportation organization). Ru. On the other hand, the information providing device 16 is shared across multiple guidance targets.

<Voice guidance device 12>
FIG. 2 is a block diagram of the voice guidance device 12. As illustrated in FIG. 2, the voice guidance device 12 includes a reproduction processing unit 32 and a sound emitting unit 34. The reproduction processing unit 32 supplies an acoustic signal S representing a guidance sound to the sound emission unit 34. The sound emission unit 34 (for example, a speaker) transmits a guidance sound according to the sound signal S supplied from the reproduction processing unit 32 It emits noise in M.

  As illustrated in FIG. 2, the reproduction processing unit 32 includes a control unit 322, a storage unit 324, and an operation unit 326. The storage unit 324 is a known recording medium such as a magnetic recording medium or a semiconductor recording medium, and stores a plurality of acoustic signals S corresponding to guidance voices having different sounding content. For example, for each of a plurality of points where the vehicle M stops (for example, a stopping point such as a train station or a bus stop), guidance voice for arriving at the point, changing at the point, and information around the point Sound signal S is stored in the storage unit 324. The operation unit 326 is an input device for receiving an operation by a transportation manager (typically, a driver of the vehicle M) HB. For example, the administrator HB can select any one guidance voice from among the plurality of guidance voices stored in the storage unit 324 by appropriately operating the operation unit 326.

  The control unit 322 is configured of, for example, a processing device such as a CPU, and centrally controls the elements of the voice guidance device 12. The control unit 322 according to the first embodiment supplies the sound output unit 34 with the sound signal S of the guidance voice selected by the administrator HB by the operation on the operation unit 326 among the plurality of sound signals S stored in the storage unit 324. . Therefore, the guidance sound is emitted from the sound emitting unit 34 for each instruction by the manager HB. The user HA in the vehicle M can listen to the guidance sound emitted from the sound emitting unit 34.

  The acoustic signal S of any one guidance voice contains identification information D for uniquely identifying the content C related to the guidance voice. FIG. 3 is a block diagram of a signal processing apparatus 200 for generating an acoustic signal S containing identification information D. As shown in FIG. A plurality of acoustic signals S sequentially generated by the signal processing device 200 of FIG. 3 are transferred to the voice guidance device 12 via, for example, the communication network 18 or a portable recording medium, and then stored in the storage unit 324.

<Signal processing device 200>
As illustrated in FIG. 3, the signal processing device 200 includes a control unit 42 and a storage unit 44. The control unit 42 of the signal processing device 200 is configured by a processing device such as a CPU, for example, and functions as a plurality of elements (component suppressing unit 422, modulation processing unit 424, mixing processing unit 426) for generating the acoustic signal S. . The storage unit 44 is, for example, a known recording medium such as a magnetic recording medium or a semiconductor recording medium. The storage unit 44 according to the first embodiment includes an acoustic signal (hereinafter referred to as an "original acoustic signal") S0 representing any one guidance voice and identification information D specific to the content C related to the guidance voice. It is memorized. The guide voice represented by the original sound signal S0 is, for example, a recorded sound of a voice actually uttered by a specific speaker or a voice generated by a known voice synthesis technology.

  FIG. 4 is an explanatory diagram of the operation of the signal processing device 200. As illustrated in FIG. 4, the original acoustic signal S0 contains an acoustic component that covers substantially the entire frequency band of the sound that can be reproduced by the sound emitting unit 34 (hereinafter referred to as “reproduction band”) B0. In the first embodiment, it is assumed that the low-performance sound emitting unit 34 can not reproduce the acoustic component of the high frequency band among the audible band from about 20 Hz to 20 kHz. Specifically, the case where the upper limit F of the reproduction band B0 of the sound emitting unit 34 is 8 kHz is illustrated. As illustrated in FIG. 4, the component suppressing unit 422 in FIG. 3 extends from the upper limit F of the reproduction band B0 by the sound emitting unit 34 to the predetermined width on the low band side of the original sound signal S0 stored in the storage unit 44. An acoustic signal SA is generated by suppressing an acoustic component of a frequency band (hereinafter referred to as “use band”) BA. For example, a low pass filter having a cut-off frequency that is lower than the upper limit F by the bandwidth of the usage band BA is used as the component suppression unit 422. The bandwidth of the utilization band BA is, for example, 2 kHz. Therefore, the use band BA is a frequency band of 6 kHz or more and 8 kHz or less included in the audible band.

  The modulation processing unit 424 in FIG. 3 generates an acoustic signal SB containing the identification information D stored in the storage unit 44. The acoustic signal SB is composed of acoustic components in the usage band BA. Although any known method may be employed for generating the acoustic signal SB containing the identification information D, for example, the method disclosed in WO 2010/016589 is preferable. Specifically, the modulation processing unit 424 sequentially performs the spreading modulation of the identification information D using the spreading code and the frequency modulation using the carrier wave in the usage band BA, to thereby use the identification information D in the usage band BA. An acoustic signal SB is generated which is contained as an internal acoustic component. The modulation processing unit 424 of the first embodiment adjusts the sound signal SB to a sufficiently small volume compared to the sound signal SA. Specifically, the volume (sound pressure level) of the sound signal SB is adjusted to a volume of about −50 dB to −80 dB with respect to the volume of the sound signal SA.

  The mixing processing unit 426 in FIG. 3 generates an acoustic signal S by combining (typically adding) the acoustic signal SA processed by the component suppressing unit 422 and the acoustic signal SB processed by the modulation processing unit 424. Do. That is, the acoustic signal S of any one guidance voice is the acoustic component of the guidance voice (acoustic signal SA) and the acoustic component of the identification information D of the content C related to the guidance voice (acoustic signal of the usage band BA And SB). The processes exemplified above are sequentially executed for each guidance voice, so that a plurality of acoustic signals S corresponding to different guidance voices are generated and transferred to the storage unit 324 of the voice guidance device 12. As understood from the above description, the acoustic signal S emitted from the sound emitting unit 34 of the voice guidance device 12 in the first embodiment is an acoustic component (acoustic signal SB) of the usage band BA in the audible band. Identification information D is included. As described above, since the sound signal SB has a sufficiently small volume compared to the sound signal SA of the guidance voice, the user HA in the vehicle M clearly perceives the guidance voice while identifying information in the usage band BA The acoustic component of D can hardly be perceived.

  As illustrated in FIG. 1, the management terminal 14 is connected to the reproduction processing unit 32 of the guidance voice system via a signal line (cable) 13. The control unit 322 of the reproduction processing unit 32 supplies the sound signal S stored in the storage unit 324 to the sound emission unit 34 as described above in response to an operation (selection of guidance voice) from the administrator HB on the operation unit 326. Then, the guidance voice is emitted and the acoustic signal S is transmitted from the signal line 13 to the management terminal 14. That is, the acoustic signal S is supplied in parallel to both the sound emitting unit 34 and the management terminal 14. Therefore, for each sound emission of the guidance sound by the sound emission unit 34, an acoustic signal S containing the identification information D of the content C related to the guidance sound is transmitted to the management terminal 14 by wire.

  The trigger for the supply of the sound signal S to the sound emitting unit 34 and the management terminal 14 is not limited to the operation from the administrator HB to the operation unit 326. For example, a configuration in which the sound signal S is supplied to the sound emitting unit 34 and the management terminal 14 triggered by the arrival of a preset time (for example, an estimated time when the vehicle M arrives at a specific point) A configuration may also be adopted in which the sound signal S is supplied to the sound emitting unit 34 and the management terminal 14 in response to the detection of the arrival of the vehicle M at a specific point by the detected detector (sensor).

<Management terminal 14>

The management terminal 14 is, for example, a portable or stationary communication terminal such as a mobile phone or a smartphone used by the administrator HB, and as illustrated in FIG. 5, the control unit 51, the storage unit 52, the communication unit 53, and the operation A unit 54 and a receiving unit 55 are provided. The communication unit 53 communicates with the information providing device 16 via the communication network 18. The operation unit 54 is an input device for receiving an operation by the administrator HB.

  The storage unit 52 is a known recording medium such as a magnetic recording medium or a semiconductor recording medium, and stores programs executed by the control unit 51 and various data used by the control unit 51. The storage unit 52 of the first embodiment stores identification information (hereinafter referred to as “guidance identification information”) G for uniquely identifying a guidance target of guidance using the management terminal 14. The receiving unit 55 receives the acoustic signal S supplied by wire from the reproduction processing unit 32 of the voice guidance device 12 through the signal line 13.

  The control unit 51 is formed of, for example, a processing device such as a CPU, and functions as an information extraction unit 512 and a provision instruction unit 514 by executing a program stored in the storage unit 52. The information extraction unit 512 extracts identification information D from the acoustic signal S received by the reception unit 55. Specifically, the information extraction unit 512 extracts the acoustic component of the use band BA containing the identification information D from the acoustic signal S by using, for example, a high pass filter, and the spreading code used for the diffusion modulation of the identification information D The identification information D is extracted by passing through a matched filter having a coefficient of.

  The provision instruction unit 514 generates a provision instruction P of the content C specified by the identification information D extracted by the information extraction unit 512. Specifically, the provision instruction unit 514 generates the provision instruction P including the identification information D extracted from the acoustic signal S by the information extraction unit 512 and the guidance identification information G stored in the storage unit 52, and the communication unit 53 To the information providing apparatus 16. Extraction of the identification information D by the information extraction unit 512 and generation of the provision instruction P by the provision instruction unit 514 are executed each time the acoustic signal S is received from the reproduction processing unit 32 of the voice guidance device 12. As described above, the reproduction processing unit 32 supplies the acoustic signal S in parallel to the sound emitting unit 34 and the management terminal 14. Therefore, extraction of identification information D of content C related to the guidance voice and generation of provision instruction P of content C specified by the identification information D are performed for each emission of the guidance voice by the sound emission unit 34 Be done.

For example, the communication unit 63 receives, from the information providing device 16, the distribution information Q including the content C related to the guidance voice. The reproduction unit 65 reproduces the content C provided from the information providing device 16. Specifically, a display device (for example, a liquid crystal display panel) that displays the image of the content C and a sound emission device (for example, a speaker or headphones) that emits the sound of the content C are used as the reproduction unit 65.

  The control unit 61 is formed of, for example, a processing device such as a CPU, and functions as a reproduction control unit 612 and an information acquisition unit 614 by executing a program stored in the storage unit 62. The reproduction control unit 612 causes the reproduction unit 65 to reproduce the content C included in the distribution information Q received from the information providing device 16. On the other hand, the information acquisition unit 614 acquires the guidance identification information G provided at the place where the guidance voice is emitted (that is, in the vehicle M).

For example, the information image X is printed on a printed matter such as an advertisement affixed in the vehicle M. The information image X is an optically readable plan view image (for example, a QR code (registered trademark)) representing guidance identification information G specific to the guidance target. The imaging unit 66 in FIG. 6 includes, for example, an imaging element capable of capturing an image, and captures an information image X in response to an instruction from the user HA to the operation unit 64. The information acquisition unit 614 identifies the guidance identification information G by demodulating the information image X captured by the imaging unit 66, and communicates a registration request R including the guidance identification information G and the terminal identification information T of the mobile terminal 20.

The registration request R is a signal for requesting registration (in other words, check-in) of the mobile terminal 20 as an object to be provided with the content C related to the guidance voice designated as the guidance identification information G. Since the guidance identification information G of any one guidance target is limitedly provided at the place where the guidance voice of the guidance target is emitted, the registration request R including the guidance identification information G of the specific guidance target is The transmitted mobile terminal 20 is estimated to be located at a place where the guidance voice of the guidance object is emitted (for example, in the vehicle M).

<Information Providing Device 16>
FIG. 7 is a block diagram of the information providing device 16. The information providing device 16 is, for example, a server device (typically, a web server) connected to the communication network 18, and includes a control unit 72, a storage unit 74, and a communication unit 76 as illustrated in FIG. . The communication unit 76 communicates with each of the mobile terminal 20 and the management terminal 14 via the communication network 18. The communication unit 76 of the first embodiment receives, via the communication network 18, the provision instruction P transmitted by the management terminal 14 and the registration request R transmitted by the mobile terminal 20. The storage unit 74 is, for example, a known recording medium such as a magnetic recording medium or a semiconductor recording medium, and stores a plurality of contents C and registration information E. As illustrated in FIG. 7, each of the plurality of contents C (C11, C12,...) Corresponds to identification information D (D11, D12,...) Unique to the contents C and the contents C. Guidance identification information G (G1, G2,...) Unique to the guidance target (vehicle M) from which the guidance voice is emitted is added.

  The registration information E designates the mobile terminal 20 to be provided with the content C related to the guidance voice of each guidance target. Specifically, as illustrated in FIG. 7, the registration information E is provided with guidance identification information G (G1, G2,...) Unique to the guidance target, and the content C related to the guidance voice of the guidance target. It is a data table in which terminal identification information T (T11, T12,...)

The registration processing unit 722 updates the registration information E in response to the registration request R transmitted from the mobile terminal 20. Specifically, of the plurality of pieces of guidance identification information G included in the registration information E, the registration processing unit 722 determines the terminal identification information T specified by the registration request R for the guidance identification information G designated by the registration request R. Make it correspond. That is, the mobile terminal 20 of the terminal identification information T designated by the registration request R is registered as a distribution target of the content C of the guidance target designated by the guidance identification information G in the registration request R.

  The information delivery unit 724 generates delivery information Q and transmits the delivery information Q from the communication unit 76 to the mobile terminal 20. Specifically, the information distribution unit 724 registers the content C of the identification information D designated by the provision instruction P received from the management terminal 14 in the registration information E for the guidance identification information G designated by the provision instruction P. It transmits to each mobile terminal 20 (namely, delivery object of the content C registered about the said guidance object). As described above, the mobile terminal 20 that has transmitted the registration request R including the guidance identification information G of the specific guidance target is estimated to be located at a place where the guidance voice of the guidance target is emitted. Therefore, the content C corresponding to the guidance voice of the guidance object is provided to the mobile terminal 20 located at the place where the guidance voice of the guidance object is emitted.

<Overall operation>
FIG. 8 is an explanatory diagram of the overall operation of the information providing system 100. As shown in FIG. The user HA who got on the vehicle M instructs the imaging of the information image X installed in the vehicle M by operating the operation unit 64 of the mobile terminal 20 of the user as appropriate. When the imaging unit 66 captures the information image X in response to an instruction from the user HA (SA1), the information acquisition unit 614 of the mobile terminal 20 receives the guidance identification information G specified from the information image X and the mobile terminal 20. The registration request R including the terminal identification information T is transmitted from the communication unit 63 to the information providing apparatus 16 (SA2).

  When the communication unit 76 receives the registration request R transmitted by the mobile terminal 20, the registration processing unit 722 of the information providing apparatus 16 transmits the registration request R for the guidance identification information G designated by the registration request R in the registration information E. The terminal identification information T designated in is registered (SA3). That is, the mobile terminal 20 in the vehicle M is added as a distribution target of the content C related to the guidance sound emitted in the vehicle M which is the guidance target.

  On the other hand, the reproduction processing unit 32 of the voice guidance device 12 supplies the sound signal S of the guidance voice selected by the administrator HB by the operation to the operation unit 326 to the sound emitting unit 34 (SA4) and via the signal line 13 It transmits to the management terminal 14 (SA5). A guidance sound is emitted from the sound emitting unit 34 by the supply of the sound signal S, and the user HA located in the vehicle M listens to the guidance sound. On the other hand, the information extraction unit 512 of the management terminal 14 extracts the identification information D of the content C related to the guidance voice by analyzing the acoustic signal S supplied from the reproduction processing unit 32 (SA6). The provision instruction unit 514 transmits a provision instruction P including the identification information D extracted by the information extraction unit 512 and the guidance identification information G held by the storage unit 52 from the communication unit 53 to the information provision device 16 (SA7).

  When the communication unit 76 receives the provision instruction P transmitted from the management terminal 14, the information distribution unit 724 of the information providing apparatus 16 identifies the content C specified in the provision instruction P among the plurality of contents C stored in the storage unit 74. The content C corresponding to the information D is specified (SA8), and one or more pieces of terminal identification information T corresponding to the guidance identification information G designated by the provision instruction P (ie, registered as a distribution target of the content C to be guided) The mobile terminal 20) is specified from the registration information E (SA9). Then, the information distribution unit 724 transmits the distribution information Q including the content C identified in step SA8 from the communication unit 76 with the mobile terminal 20 of each terminal identification information T identified in step SA9 as a destination (SA10).

  When the communication unit 63 receives the distribution information Q transmitted from the information providing apparatus 16, the reproduction control unit 612 of the mobile terminal 20 causes the reproduction unit 65 to reproduce the content C included in the distribution information Q (SA11). As understood from the above description, in the vehicle M which is the guidance object, the guidance sound regarding the guidance object is sequentially emitted from the sound emitting unit 34 in the vehicle M, while for each emission of the guidance sound, The content C related to the guidance voice is sequentially reproduced by the reproduction unit 65 of the mobile terminal 20. That is, the content C related to the guidance voice is sequentially reproduced on the mobile terminal 20 in conjunction with the emission of the guidance voice. Therefore, the user HA in the vehicle M can sequentially listen to the guidance voice and can sequentially view the content C related to the guidance voice.

  The condition that the predetermined time (the time when the user HA is expected to be located in the vehicle M) has elapsed since the registration processing unit 722 of the information providing device 16 adds the terminal identification information T to the registration information E Then, the terminal identification information T is deleted from the registration information E. That is, the mobile terminal 20 of the terminal identification information T is excluded from transmission targets of the distribution information Q. Therefore, the distribution information Q is not transmitted to the mobile terminal 20 of the user HA who got off the vehicle M. The condition for deleting the terminal identification information T from the registration information E is not limited to the above example (elapsed time). For example, the terminal identification information T of the mobile terminal 20 may be deleted from the registration information E in response to a deletion request transmitted from the mobile terminal 20 to the information providing apparatus 16 in response to an operation from the user HA to the operation unit 64. It is possible.

  As described above, in the first embodiment, the mobile terminal for which the provision instruction P of the content related to the guidance voice is generated for each emission of the guidance voice by the sound emitting unit 34 and registered as the distribution target in the registration information E The distribution information Q of the content C related to the provision instruction P is transmitted to the information 20. Therefore, it is possible to reproduce the content C related to each guidance voice of guidance object in conjunction with the sound emission of the guidance voice on the mobile terminal 20.

  Further, in the first embodiment, when the information providing apparatus 16 receives from the mobile terminal 20 a registration request R including the guidance identification information G which can be acquired at the place (in the vehicle M) where the guidance voice is emitted. The mobile terminal 20 is registered as a provision target of the content C related to the guidance voice. Therefore, it is possible to limit the provision object of the content C related to the guidance voice to the mobile terminal 20 located at the place where the guidance voice is emitted. In the first embodiment, in particular, the registration request R including the guidance identification information G acquired by the mobile terminal 20 by the imaging of the information image X installed at the place where the guidance voice is emitted is transmitted from the mobile terminal 20, There is an advantage that the configuration and procedure for causing the mobile terminal 20 to acquire the guide identification information G are simplified.

  In the first embodiment, the guidance sound is emitted from the sound emitting unit 34 by the supply of the acoustic signal S, while the identification information D contained as an acoustic component in the acoustic signal S is extracted by the management terminal 14 The provision instruction P is then generated. That is, the sound signal S is shared by the sound emission of the guidance voice by the sound emission unit 34 and the extraction of the identification information D by the management terminal 14. Therefore, it is possible to easily interlock the emission of the guidance sound by the sound emission unit 34 and the transmission of the provision instruction P by the provision instruction unit 514 (and thus the provision of the content C to the mobile terminal 20).

  The sound volume in the utilization band BA in which the sound component of the identification information D is contained is suppressed to a sufficiently low sound volume as compared with the sound component (sound signal SA) of the other band. Therefore, even when the volume of the sound component of the identification information D is sufficiently suppressed so that the user HA who listens to the sound emitted from the sound emitting unit 34 does not easily perceive the sound component of the identification information D There is an advantage that the identification information D can be extracted from S with high accuracy.

  By the way, as a configuration for extracting the identification information D contained in the sound signal S by the management terminal 14, for example, from the sound signal obtained by collecting the sound emitted by the sound emitting unit 34 by the management terminal 14 A configuration for extracting the identification information D (hereinafter, referred to as “contrast example”) may also be assumed. However, in the comparative example, since noise is superimposed on the sound on the path from the sound emitting unit 34 to the management terminal 14, it may be difficult as a result to extract the identification information D with high accuracy in the management terminal 14. . In the first embodiment, since the sound signal S containing the identification information D is transmitted from the voice guidance apparatus 12 to the management terminal 14 by wire, the influence of noise on the sound signal S is reduced. Therefore, according to the first embodiment, as compared with the comparative example, there is an advantage that the identification information D can be extracted from the acoustic signal S with high accuracy. However, the above description is not intended to exclude the comparative example from the scope of the present invention, and the comparative example can be included in the scope of the present invention.
